hi francois
in platform (nordic nrf52840,sdk 15.3)
i add the section(image_hdr) ,so it will be overlapping.
to use mergerhex to merger,not use nrfjprog (loadfile to change the [Unique Parameters)
nrf_common.ld
ENTRY(Reset_Handler)
SECTIONS
{
.text :
{
KEEP((.isr_vector))
KEEP ((.image_hdr))
(.text)
…
}
}
